ABSTRACT:
A method of calibrating and using a device for the determination of the concentration of an active gas in a mixture of gases wherein the device incorporates a gas sensor (4) and has gas diffusion barrier means (A) and (B), one of which may be closed by a valve (12). The signal from the sensor is recorded at first and second times after closing the valve, and a value for the concentration of an active gas is calculated from the signals and the time difference.
